Hydrogel electrolytes are ideal for flexible wearable electronic devices because of their high ionic conductivity, flexibility, and biocompatibility. However, some problems, such as poor mechanical properties, low conductivity, and lack of adhesivity, are encountered in the process of hydrogel preparation and application, which restrict the further development of hydrogel electrolytes. In this study, PVA was used as the first network, and P(AM-co-AMPS) as the second network to prepare a double-network hydrogel electrolyte. Laponite and Na2SO4 were introduced into the hydrogel during hydrogel formation as the nanofiller and salt with the salting-out effect to enhance its mechanical properties. The hydrogel electrolyte with high toughness (1663 kJ·m–3), adhesivity (77 kPa), and ionic conductivity (1.7 S·m–1) was obtained. In addition, the hydrogel electrolyte also has excellent antifatigue performance. In the 10 consecutive tensile cycles, the tensile strength does not decay. Due to the high adhesivity of the hydrogel electrolyte, a symmetrical all-solid-state supercapacitor was assembled with a tight interface between the hydrogel electrolyte and the AC/CNT composite electrode. The supercapacitor has a high specific capacitance of 186.1 mF·cm–2 at the current density of 1 mA·cm–2. In addition, the capacitor has good flexibility and can withstand bending at various angles. The hydrogel electrolyte also has excellent strain sensing performance, with an ultrafast tensile response time (0.17 s) and high sensitivity factor (GF = 10.01). Finally, the self-powered sensor system composed of a supercapacitor as the power supply device and hydrogel electrolyte as the sensing part was obtained and applied to human motion monitoring, which provides a potential application in the integrated flexible electronic system.

Water management in high-temperature and high-salinity reservoirs remains a critical challenge for oilfield operations, with conventional polymer gel systems exhibiting insufficient thermal stability and salt tolerance under extreme conditions. Here, we establish an integrated computational–experimental platform combining density functional theory (DFT) and molecular dynamics (MD) simulations to rationally design a novel AM/AMPS/AMB (Acrylamide/2-acrylamido-2-methylpropanesulfonic acid/sodium 3-acrylamido-3-methylbutanoate) terpolymer gel plugging agent tailored for the Tahe Oilfield (140 °C, Ca2+/Mg2+10,000 mg L−1). Density functional theory (DFT) calculations of fourteen functional monomers identified AMB as the optimal candidate, achieving further hydrogen bond interactions that stabilize the crosslinked architecture under extreme conditions. This computational pre-screening reduced experimental iterations by over 60% and significantly shortened development cycles compared to conventional trial-and-error approaches. Experimentally, the optimized terpolymer exhibited a 40% increase in storage modulus (150 Pa) relative to AM/AMPS binary systems, 25% improvement in thermal stability (residual carbon at 300 °C), and plugging efficiency exceeding 92% in core flooding tests.

High water cut of produced fluid is one of the most common problems in reservoir development. At present, injecting plugging agents and other profile control and water plugging technologies are the most widely used solutions. With the development of deep oil and gas resources, high-temperature and high-salinity (HTHS) reservoirs are becoming increasingly common. Conventional polymers are prone to hydrolysis and thermal degradation under HTHS conditions, making polymer flooding or polymer-based gels less effective. Phenol–aldehyde crosslinking agent gels can be applied to different reservoirs with a wide range of salinity, but there exist the disadvantage of high cost of gelants. The cost of water-soluble phenolic resin gels is low. Based on the research of former scientists, copolymers consisting of acrylamide (AM) and 2-Acrylamido-2-Methylpropanesulfonic acid (AMPS) and modified water-soluble phenolic resin were used to prepare gels in the paper. The experimental results show that the gelant with 1.0 wt% AM-AMPS copolymer (AMPS content is 47%), 1.0 wt% modified water-soluble phenolic resin and 0.4 wt% thiourea has gelation time of 7.5 h, storage modulus of 18 Pa and no syneresis after aging for 90 days at 105 °C in simulated Tahe water of 22 × 104mg/L salinity. By comprehensively comparing the effectiveness of the gels prepared by a kind of phenolic aldehyde composite crosslinking agent and modified water-soluble phenolic resin, it is found that the gel constructed by the modified water-soluble phenolic resin not only reduces costs, but also has shorter gelation time and higher gel strength. The oil displacement experiment with a visual glass plate model proves that the forming gel has good plugging ability and thus improves the sweep efficiency. The research expands the application range of water-soluble phenolic resin gels, which has an important implication for profile control and water plugging in the HTHS reservoirs.Keywords:low-cost gel;AM-AMPS copolymer;high-temperature and high-salinity resistant gel;oil displacement experiment

A novel hydrophobic association copolymer (PAMA) was synthesized by incorporating acrylamide (AM), 2-acrylamide-2-methylpropanesulfonic acid (AMPS), cationic monomer (MEDDA), and methyl methacrylate (MMA). The properties of MMA copolymers with varying contents were analyzed using infrared spectroscopy, nuclear magnetic resonance spectroscopy, and scanning electron microscopy. Optimal overall performance of the solution was achieved when the MMA content reached 1.4 % w/w. Compared to pure PAAM (without MMA), the PAMA-1.4 % polymer exhibited superior viscoelasticity, temperature resistance, and shear resistance. This enhancement in PAMA performance can be attributed to the significant inhibition of intermolecular water film formation within the polymer matrix by MMA, effectively improving and regulating solution solubility while strengthening molecular chain interactions and enhancing the structural network strength of PAMA polymers. Additionally, the inclusion of MMA transformed rock surfaces from non-wetting to wetting conditions, thereby greatly improving oil displacement efficiency. In displacement experiments, PAMA-1.4 % performed better in terms of enhanced oil recovery, the recovery rate of 0.1 % w/w PAMA-2.4 % solution is only 7.78 %, while the recovery rate of 0.1 % w/w PAMA-1.4 % solution is 13.06 %.

Salecan is a novel water-soluble extracellular β-glucan and has excellent physicochemical and biological properties. A series of hydrogels were fabricated from Salecan and poly(2-acrylamido-2-methylpropanesulfonic acid- co - N -hydroxymethyl acrylamide) (poly(AMPS- co -HMAA), PAH) by semi-IPN technique. The introduction of Salecan into the PAH network endows the system with enhanced cell adhesion properties. These semi-IPN hydrogels with open interconnected pores had pH and salt-sensitive swelling behavior. The increase in the content of hydrophilic Salecan could enhance the water uptake of the hydrogels. Rheological results indicated that the incorporation of PAH into hydrogels increased the storage modulus. The degradation property of the hydrogels can be tuned by modulating the content of Salecan and BAAm. Cytotoxicity results revealed that the hydrogels were non-toxic to COS-7 cells. All these results suggested that Salecan/PAH semi-IPN hydrogels exhibited great potential for applications in soft tissue engineering.

The practical deployment of aqueous zinc-ion batteries (AZIBs) in large-scale energy storage applications is hampered by short cycle lifespans and limited zinc utilization due to uncontrollable dendrite growth and water-induced side reactions. Herein, we propose an environmentally friendly electrolyte additive, 2-acrylamido-2-methylpropanesulfonic acid (AMPS), which features dual zincophilic sites and a hydrophobic group, to enhance Zn stability. Theoretical calculations and experimental characterizations demonstrate that AMPS can firmly adsorb onto the Zn (0 0 2) plane through its dual zincophilic sites ( SO 3 H and NH CO), while the C C hydrophobic group orients toward the electrolyte, ultimately forming a stable zincophilic/hydrophobic interface on the Zn electrode in situ. This unique structure not only inhibits water-induced side hydrogen evolution reactions but also induces preferential deposit propagation along the (0 0 2) crystal plane. Benefiting from this synergetic effect, the Zn//Cu asymmetric cell with AMPS electrolyte maintains an ultrahigh average coulombic efficiency of 99.8 % for over 2500 cycles at 2 mA cm −2 , achieving 1 mAh cm −2 . Furthermore, the Zn//MnO 2 full cell shows a high-capacity retention of 67.7 % at 1.8 A g −1 after 1000 cycles, confirming the effectiveness of the AMPS additive in improving the cyclability and performance of AZIBs.

Scorpion venoms are rich resources of antimicrobial peptides (AMPs). While the short-chain noncysteine-containing AMPs have attracted much attention as templates for drug development, the antimicrobial potential of long-chain noncysteine-containing AMPs has been largely overlooked. Here, by using the online HeliQuest server, we designed and analyzed a series of 14-residue fragments of Smp43, a 43-residue long-chain noncysteine-containing AMP identified from the venom ofScorpio maurus palmatus. We found that Smp43(1-14) shows high antimicrobial activity against both Gram-positive and Gram-negative bacteria and is nontoxic to mammalian cells at the antimicrobial dosage. Sequence alignments showed that the designed Smp43(1-14) displays a unique primary structure that is different from other natural short-chain noncysteine-containing AMPs from scorpions, such as Uy17, Uy192 and IsCT. Moreover, the peptide Smp43(1-14) caused concentration-dependent fluorescence increases in the bacteria for all of the tested dyes, propidium iodide, SYTOXTMGreen and DiSC3-5, suggesting that the peptide may kill the bacteria through the formation of pore structures in the plasma membrane. Taken together, our work sheds light on a new avenue for the design of novel short-chain noncysteine-containing AMPs and provides a good peptide template with a unique sequence for the development of novel drugs for use against bacterial infectious diseases.Keywords:scorpion venom;noncysteine-containing AMPs;Smp43;Smp43(1-14);antimicrobial resistance;HeliQuestKey Contribution:Smp43(1-14), a short fragmented peptide of Smp43, was designed as a novel antimicrobial peptide with a unique sequence and potent antimicrobial activity.

Among the Cu(II) removal methods, adsorption is a favorable technique and has attracted large attention because of its effectiveness and low cost. In quest of seeking for a favorable adsorbent with a high Cu(II) adsorption capacity and excellent reusability, researchers have paid much attention to hydrogels with three-dimensional networks. In this study, a novel hydrogel (P(AMPS-co-VDT) hydrogel) based on free-radical polymerization was synthesized with ionic monomer sodium 2-acrylamido-2-methylpropane sulfate (AMPS-Na + ) and 2-vinyl-4, 6-diamino-1, 3, 5-triazine (VDT) and applied for Cu(II) adsorption in aqueous solutions. The hydrogel was characterized for swelling performance, surface morphology, functional groups, thermal gravimetric behavior, and elements. The maximum Cu(II) adsorption capacity (175.75 mg/g) was relatively high compared with other hydrogels. The P(AMPS-co-VDT) hydrogel also was found to have a relatively good Cu(II) desorption and reuse behavior. The adsorption mechanism could be chelation and ion exchange. This work provides a new hydrogel for effective Cu(II) removal in the future.

Soil ruins hold historical significance and serve as witnesses to past civilizations. High temperatures cause soil moisture to evaporate and soil to shrink, leading to cracking issues and making preservation a global challenge. P(AA-AM-AMPS) (Acrylic acid -Acrylamide-2-Acrylamide-2-methy-propenesulfonic acid) composites solve this problem by combining absorbent materials with loess. In this study, P(AA-AM-AMPS) was prepared using a solution method. The water absorption, water retention, air permeability, and compressive strength of P(AA-AM-AMPS) in loess were studied. The results show that after adding P(AA-AM-AMPS) to loess, there is no obvious color difference compared with the blank sample, and the air permeability of the reinforced loess is basically the same as that of the blank soil. After aging resistance tests, the surface cracking of soil clods is significantly reduced compared to that of the blank samples, and their compressive strength improved from 1.8 N/mm2to 2.6 N/mm2.

The poly(methyl methacrylate-ethylene glycol dimethacrylate-2-acrylamido-2-methylpropanesulfonic acid) [poly(MMA-EGDMA-AMPS)] microsphere was produced by a soap-free emulsion polymerization of MMA, EGDMA and AMPS. The chemical composition, morphology, particle size distribution and properties of the obtained microspheres were characterized by energy dispersive spectrometer (EDS), Fourier transform infrared (FTIR) spectroscopy, scanning electron microscopy (SEM), a laser particle analyzer and thermogravimetric analysis (TGA). Results showed that the microspheres had a high-quality spherical morphology, irrespective of the components, and their particle sizes mainly ranged from 10 μm to 70 μm. The microspheres were thermally stable up to 190°C. As the AMPS loading was increased, the synthetic yield rate decreased and the water uptake increased. The optimum synthetic yield rate and water uptake were obtained at a 2.0 wt% AMPS. In addition, the selected microspheres with a diameter of approximately 25 μm provided an effective plugging, and the plugging rate was up to 80%. This study demonstrated that the plugging behavior of microspheres was due to their deformation, migration and aggregating properties in the plugging process, which made them potential materials for modifying the porous reservoir to enhance oil recovery in petroleum engineering.

In order to reduce the pollution of the bio-waste cabbage to the environment and achieve recycling of biological waste resources, synthesis of a novel superabsorbent polymer gel based on waste cabbage (CB) using two monomers AMPS (2-acrylamide-2-methyl-1-propane sulfonic acid) and AA (acrylic acid). And the synthesis conditions were optimized, such as the ratio of AMPS and AA, initiator content, and crosslinker content. And the water retention, salt resistance and repeated swelling performance were investigated too. The chemical structure thermal stability and microscopic appearance of the superabsorbent polymer gel were investigated by Fourier transform infrared spectroscopy (FTIR), Thermal gravimetric analysis (TGA) and Scanning electron microscope (SEM). The results showed that the novel superabsorbent polymer gel exhibits excellent water absorbency, which can absorb ultrapure water, distilled water, tap water and 0.9% NaCl solution are 1914 g/g, 1726 g/g, 306 g/g and 114 g/g, respectively. This is higher than in related studies 30%− 40% in distilled water, 60%− 70% in tap water and 10%− 20% in 0.9% NaCl solution. Therefore, this superabsorbent polymer gel showed a high swelling property and stable salt resistance. It has a broad application prospect.

Synthesis of acrylamide-based polymers with excellent stability is crucial for oilfield applications. In this study, a novel modified silica nanoparticle (MSiO2) obtained by a two-step N-acylation reaction was used as a functional monomer to enhance the stability of poly(acrylic acid (AA)/2-acrylamido-2-methyl-1-propanesulfonic acid (AMPS)/acrylamide (AM)) ternary polymer (NSPM). A novel poly(MSiO2/AA/AMPS/AM) quaternary copolymer (MSPM) was obtained in this manner. The microstructure of MSPM was characterized by Fourier transform infrared (FTIR), scanning electron microscopy (SEM), and energy-dispersive spectroscopy (EDS). The rheological properties of the MSPM were investigated based on the apparent viscosity in different salinities, temperatures, and shear rates. The MSPM exhibited improved stability compared with NSPM when the MSiO2 content was within the range of 0.14–0.20 wt %. This enhancement may be associated with hydrogen-bond-mediated intermolecular associations and MSiO2-centered branched or locally cross-linked structures formed during polymerization. Furthermore, the application of MSPM to gelation experiment showed that the grafting of MSiO2 effectively improved the gel strength of the polymer and prolonged its gel stabilization time from 10 to 14 days. The results of molecular dynamics simulation (MDS) demonstrate that the addition of MSiO2 effectively enhances the interaction between water and MSPM gel, which explains the fact that MSiO2 can reduce the dehydration rate of the MSPM gel.
